In tcp_close()= the socket buffers are relinquished, but the clean up of associated state would only be done later in tcp_discardcb().=20 The change exposing this was to no longer discard the SACK scoreboard immediately with a Retransmission timeout, in order to avoid unneccessary retransmissions in such an event. The SACK scoreboard is used for transmiss= ion selection during loss recovery or retransmission timeouts. Additionally, timers could be restarted after having sent a RST packet from tcp_drop() - while the session was already closed. In summary, it appears that there always existed the problem of inconsistent state in between tcp_close() and tcp_discardcb(), where a timer could trigg= er. However, as an RTO would previously clean the SACK scoreboard state, this w= ould not lead to external visible misbehavior or a panic. The three commits address these issues individually - clean any SACK state together with releasing the socket buffer - stop re-arming any timers in the case of sending a RST (while in CLOSED state) - stop timers in tcp_close() instead of waiting for the final clean-up of t= cpcb state in tcp_discardcb(). --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Sat Feb 10 10:25:32 2024 X-Original-To: transport@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4TX6LN5Tczz59QFf for ;
